Supplier of CRPA Antennas for Russian Drones Unveils New 32-Element Model

Chinese company Harxon, which produces CRPA antennas used in Russian kamikaze drones, has presented a new 32-element model.

According to the Colonel GSh defense-focused outlet, the antenna was showcased at the DWC2026 exhibition.

The new system is designed to protect satellite navigation signals from jamming and spoofing during intensive electronic warfare operations.

The system measures 390 × 390 × 52 mm and weighs less than 6.5 kg. Its power consumption is rated at up to 90 W.

The antenna features 32 elements and can simultaneously suppress up to 31 interference sources. The claimed jamming suppression level exceeds 80 dB, while the interference protection effectiveness exceeds 105 dB.

The system uses an RS-232 interface for data transfer and operates on a 17–32 V power supply. Its operating temperature range extends from −40°C to +70°C.

CRPA systems like this are widely used to enhance the electronic warfare resistance of strike drones, missiles, and other precision-guided weapons, helping maintain reliable satellite navigation under heavy jamming conditions.

Harxon has reportedly been supplying CRPA antennas to Russia, disguising them as agricultural machinery equipment.

What are CRPA systems?

CRPA (Controlled Reception Pattern Antenna) is a type of multi-element satellite navigation antenna system designed to protect GPS/GNSS receivers from electronic jamming and spoofing.

The technology uses multiple antenna elements together with digital signal processing to create a controlled reception pattern, allowing the system to suppress interference and maintain reliable navigation signals.

CRPA technology allows the antenna to block jamming signals arriving from certain directions while continuing to receive legitimate satellite navigation signals.

Its main purpose is to keep GPS/GNSS navigation functioning reliably during heavy electronic warfare. These systems can automatically identify sources of interference and reduce their effect on the navigation receiver.
